Here is the 1910 US census for my great grandfather's younger brother, Fred Emery (last entry).
By 1910, Frank had moved from Mitchellville, to Des Moines, Iowa. Frank was 18 and working at a lumberyard, living as a 'roomer' at the home of Violet Earhart.
It's possible he could have been related as the name above Frank indicates "William Emery". William Emery was a cousin of Violet Earhart, the head of the household.
